I'll throw in my .02 as someone who went from PS to FT over the summer and actually did it at 25nl fr as well (although I apologize I don't have specific #s to share).

The bonuses are way better at Ft. I believe it's a bit easier to earn them and the signup bonus is a big gimmie esp for someone like you playing uber hands/hr at a solid level. And sometimes they just throw them at you and say 'here is 100 bucks' as they did in Dec. Seriously all I had to do was click OK to accept the bonus. Nothing else. As mentioned above there are a bunch of neat little sidebars such as iron man as well. I would also say that at 25nl at least ft is a bit softer. Nothing dramatic but imo it's noticeable.

I don't know the #s on rakeback as I wasn't smart enough to do that back then. But the ps rake program is a bitch and I'm writing this on my phone so I have to stop here but i would. be happy to answer any questions u have.
